Få fat på icon fra anden process?

hmm. hvis du kan få fat på filnavnet kan det vel nok lade sig gøre

Få alle moduler som processen bruger: (den første må være stien til selve programmet, som vi skal hente ikonet ud fra)

//Get all modules inside the process
Process[] ObjModulesList = Process.GetProcessesByName("devenv");

// Populate the module collection.
ProcessModuleCollection ObjModules = ObjModulesList[0].Modules;

// Iterate through the module collection.
foreach (ProcessModule objModule in ObjModules)
{
//Get valid module path
strModulePath =GetValidString(objModule.FileName.ToString());
//If the module exists
if (File.Exists(objModule.FileName.ToString()))
  {
    //Get version
    string strFileVersion = GetValidString(objModule.
                  FileVersionInfo.FileVersion.ToString());
    //Get File size
    string strFileSize    = GetValidString
                (objModule.ModuleMemorySize.ToString());
    //Get Modification date
    FileInfo objFileInfo = new
                FileInfo(objModule.FileName.ToString());
    string strFileModificationDate = GetValidString
        (objFileInfo.LastWriteTime.ToShortDateString()); 
    //Get File description
    string strFileDescription  = GetValidString
                  (objModule.FileVersionInfo.
                  FileDescription.ToString());
    //Get Product Name
    string strProductName  = GetValidString
          (objModule.FileVersionInfo.ProductName.ToString());
    //Get Product Version
    string strProductVersion  = GetValidString
          (objModule.FileVersionInfo.ProductVersion.ToString());
  }
}


Hente ikon fra fil:

GetFileIcon is used to obtain icons for files, and uses three parameters:

name - Complete file and path names to read.
size - Whether to obtain 16x16 or 32x32 pixels, uses the IconSize enumeration.
linkOverlay - Specify whether the returned icon should include the small link overlay.
It is a static member function since it doesn't need to store any state, and is intended primarily as an added layer of abstraction. If I needed to obtain a file's icon in the future (and not store it in an ImageList etc.) then I could do so using this class. Once I had a type that wrapped up the necessary API functions to obtain file icons I would then build another type to manage large and small ImageLists that would enable me to make a single call to add an icon, and if it was already added, return the index that the icon was in the ImageList.

public static System.Drawing.Icon GetFileIcon(string name, IconSize size,
                                              bool linkOverlay)
{
    Shell32.SHFILEINFO shfi = new Shell32.SHFILEINFO();
    uint flags = Shell32.SHGFI_ICON | Shell32.SHGFI_USEFILEATTRIBUTES;
   
    if (true == linkOverlay) flags += Shell32.SHGFI_LINKOVERLAY;


    /* Check the size specified for return. */
    if (IconSize.Small == size)
    {
        flags += Shell32.SHGFI_SMALLICON ; // include the small icon flag
    }
    else
    {
        flags += Shell32.SHGFI_LARGEICON ;  // include the large icon flag
    }
   
    Shell32.SHGetFileInfo( name,
        Shell32.FILE_ATTRIBUTE_NORMAL,
        ref shfi,
        (uint) System.Runtime.InteropServices.Marshal.SizeOf(shfi),
        flags );


    // Copy (clone) the returned icon to a new object, thus allowing us
    // to call DestroyIcon immediately
    System.Drawing.Icon icon = (System.Drawing.Icon)
                        System.Drawing.Icon.FromHandle(shfi.hIcon).Clone();
    User32.DestroyIcon( shfi.hIcon ); // Cleanup
    return icon;
}

hvor den sætter Form1 text til det fulde filnavn og ikonet på fomen til ikonet på den process du har fat på

øh, okay. Mange tak!
Meget detaljeret svar ;)
Så skal jeg bare finde ud af hvordan man ændre position og størrelse på en anden proces's vindue, men det laver jeg lige et andet spørgsmål til...
